Probable Cause
DC converter is not
plugged into a reliable
power supply or not
connected securely to the
computer's DC-In port.
Surge protector is not
turned on and/or plugged
in.
Power supply cabling is
shorted to the computer.
Memory is not seated
correctly or is faulty.
BIOS is corrupt.
System cannot find a
proper bootable sector on
the boot device.
Ribbon cable or power
connector not installed
correctly
Master/Slave jumpers not
configured on hard drives.
Hard drive parameters in
BIOS are incorrect.
Hard drive not seen in
FDISK
Recommended Solution
Ensure the converter is plugged into an electrical
outlet (and surge protector if present) and into the
DC-In port of computer. Often power cords can
become inadvertently disconnected.
If you are using a surge protector, ensure the
surge protector is turned on and plugged in to the
electrical outlet.
Ensure the power supply cabling is not shorted to
the computer. Reposition the power supply cables
to the computer chassis so they are not pinched or
crimped.
(In case of a short, the power supply will sense the
short and shut off. When the short is removed, the
power supply should automatically sense the
removal of the short and restore operation. If
cables become damaged, contact Kontron for
repair or replacement
1 beep, 2 beeps, or 3 beeps:
Re-seat the memory first. If that does not fix the
problem, replace the memory with known good
chips.
If your system still fails to boot after reseating the
memory and checking cables and boards, try
reflashing the BIOS with the latest version, if
possible.
Install an operating system on the hard drive or
boot from a floppy disk.
Confirm correct cabling to the hard-drive ribbon
cable and power connectors.
Configure the "Master/Slave" jumpers on the hard
drives. When sharing a single IDE channel, one
drive must be Master and the second drive must
be configured as Slave.
Confirm hard-drive parameters in the BIOS setup
are correct. Auto-detect the drives and confirm
detected parameters are correct for the hard
drives.
Verify that the hard drive is seen in FDISK and run
FDISK/mbr from boot floppy.
